The Fecal Porphyrin Profile In River Otters As A Biomarker Of The Effects Of Oil Exposure, Christopher Taylor

Marine Biology

The use of profiles of fecal porphyrins in river otters as a biomarker of the effects of oil exposure was investigated. A high-performance liquid chromatography method was developed to quantify porphyrins and compared to a spectrofluorometric method. Profiles of porphyrins were characterized in fecal samples collected at oiled and nonoiled areas in Prince William Sound following the Exxon Valdez oil spill. Levels of porphyrins in fecal samples indicated a temporal pattern of physiological stress and recovery similar to that described by other biomarker studies. Profiles of porphyrins were also characterized in fecal samples from southeast Alaska and contributed to the …

Acute Toxicity Of The Oil Dispersant Corexit 9500, And Fresh And Weathered Alaska North Slope Crude Oil To The Alaskan Tanner Crab (C. Bairdi), Two Standard Test Species, And V. Fischeri (Microtox Assay), Sara Louise Rhoton

Marine Biology

Toxicity assays of the oil dispersant Corexit 9500, and fresh and weathered Alaska North Slope (ANS) crude oil were conducted on Alaskan tanner crab larvae (Chionoecetes bairdi) under cold-region conditions, the reference species, Mysidopsis bahia and Menidia beryllina, and Vibrio fischeri (Microtox bioassay). Acute 96-hour toxicity data for C. bairdi were calculated using the response 'affected' (decreased phototactic response and ability to swim). C. bairdi were most sensitive to non-dispersed weathered oil (EC₅₀=0.4 mg/L), least to dispersant-only solutions (EC₅₀=1,267 mg/L), and were typically more sensitive than the reference species. Dispersant-only solutions were consistently least toxic for all species tested. Dispersed …

Secondary Reproductive Strategies In Pacific Black Brant (Branta Bernicla Nigricans), Pamela A. Svete

Biological Sciences

Waterfowl are known to use secondary reproductive strategies, both extra-pair copulations and intraspecific brood parasitism, to increase fitness. We used five polymorphic microsatellite loci to determine extra-pair paternity and nest parasitism in 30 nests of Pacific Black Brant geese (Branta bernicla nigricans) containing 108 offspring. Fourteen of the 30 nests contained offspring that were not genetically related to one or both of the attending adults: 6.5% (7/108) of the offspring resulted from extra-pair copulations (EPC); 13.9% (15/108) of the offspring resulted from intraspecific brood parasitism (IBP). All offspring resulting from EPCs were produced during the peak period of nest initiation. …

Wavelength-Specific Fluorescence Coefficients For Simulating Hyperspectral Reflectance Signatures Of Water, Charles R. Bostater, Jan Rebman

Ocean Engineering and Marine Sciences Faculty Publications

A model1'2 which describes the transfer of irradiant light in water is used to predict the fluorescence response ofthe water surface reflectance under solar induced or an artificial light source such as a laser. Formulations for the estimation of wavelength dependent fluorescent coefficients. The techniques allows the description ofa fluorescence reflectance response in deep and shallow waters with various bottom reflectance signatures such as submerged vegetation, corals and sand. Recent advances in the model are presented for obtaining wavelength dependent fluorescence spectrum responses from the solutions of the two flow equations following the procedures developed by Bostater1'2'3. Synthetic or modeled …

Differential Regulation Of The Uncoupling Protein 1 Gene, Stephen R. Lepage

Biological Sciences

The mouse uncoupling protein 1 gene (Ucpl) is expressed specifically in brown adipose tissue and its transcription is increased by cold exposure. We have analyzed the transcriptional control of this gene through deletion analysis of the upstream untranslated regions of Ucpl. Mutated minigene constructs were microinjected into mouse pronuclei to generate transgenic mice. Positive transgenic founders were crossed with Balb/cByJ +/+ mice to generate F₁ offspring heterozygous for the transgene, which were then examined for tissue-specific and cold inducible expression of the minigenes by northern analysis. Protein-DNA interactions at putative regulatory sites were also explored through in vitro gel shift …

Putative Pheromones In The Urine Of Male Moose: Evolution Of Honest Advertisement?, Chris Linda Whittle

Biological Sciences

I tested hypotheses about how olfactory communication is related to mating behavior in Alaskan moose (Alces alces gigas). Males dig rutting pits where urine is deposited to which females strongly respond. Consequently, male urine may contain primer pheromones that synchronize estrus of females. Urine samples were collected from captive moose on the Kenai Peninsula, Alaska. Samples included those from the mating season and from the nonrutting period for two adult males, one yearling male, and one male and one female calf. After pH adjustment, samples were extracted with methylene chloride to yield 3 fractions (acidic, neutral, and basic), which were …

Ecology Of Mountain Sheep: Effects Of Mining And Precipitation, Michael William Oehler

Biological Sciences

We examined effects of mining on mountain sheep (Ovis canadensis nelsoni) in California. Size of home range, forage quality, and diet did not differ between populations in mined and nonmined areas. During summer, we observed the greatest disparity in time spent feeding and diet quality. Because of their dependence on a spring adjacent to the mine, sheep may have spent more time vigilant, and less time feeding. Reducing mining during summer may benefit sheep. We also compared ecology of two female mountain sheep populations from different areas (xeric vs. mesic) in the Mojave Desert. The more xeric Panamint Range was …

Studies On The Ecological Physiology Of Porphyra Abbottae And Porphyra Torta (Rhodophyta): Development Of New Species For Mariculture In Alaska, Jan Marie Conitz

Fisheries

Environmental factors affecting the distribution and growth of Porphyra abbottae and Porphyra torta were studied in a research project on the feasibility of nori mariculture in southeast Alaska. In situ abundance of Porphyra abbottae was compared at sites in Sitka Sound, Cross Sound and Chatham Strait. Growth of laboratory cultured Porphyra torta gametophytes was studied in response to nutrients, salinity, crowding and substrate. The seasonal progression of abundance in Porphyra abbottae varied between study sites, with associated differences in water motion and temperature. Double sampling techniques improved accuracy of in situ abundance estimates. Germination and initial growth of cultured Porphyra …

A Transiting "51 Peg-Like" Planet, Gregory W. Henry, Geoffrey W. Marcy, R. Paul Butler, Steve Vogt

Information Systems and Engineering Management Research Publications

Doppler measurements from Keck exhibit a sinusoidal periodicity in the velocities of the G0 dwarf HD 209458, having a semiamplitude of 81 m s^-1 and a period of 3.5239 days, which is indicative of a "51 Peg-like" planet with a minimum mass (M sin i) of 0.62 M_Jup and a semimajor axis of 0.046 AU. Follow-up photometry reveals a drop of 0.017 mag at the predicted time (within the errors) of transit by the companion based on the velocities. This is the first extrasolar planet observed to transit its star. The radius of the planet derived …

Results Using An Alternative Approach To Channel Equalization Using A Pattern Classification Strategy, Frank M. Caimi, Gamal A. Hassan

Electrical Engineering and Computer Science Faculty Publications

In underwater acoustic communication, (ACOMMs), ocean surface and bottom conditions create multi path propagation's for the transmitted signal that result in Inter symbol Interference (ISI) at the receiver. Generally, Equalization, Diversity IBeam forming, and Channel Coding are three independent techniques that are used to improve received signal quality. Equalization compensates for ISI created by a band-limited, time-dispersive channel through implementation of specialized filtering schemes within the receiver. The coefficients of the equalizer need to be continuously adjusted to compensate for the variability in the channel. Since the number of states required by the equalizer (or beam former) is finite, and …

Electrical Resistivity Of A Thin Metallic Film, Horacio E. Camblong

Physics and Astronomy

The electrical resistivity of a pure sample of a thin metallic film is found to depend on the boundary conditions. This conclusion is supported by a free-electron model calculation and confirmed by an ab initio relativistic Korringa-Kohn-Rostoker computation. The low-temperature resistivity is found to be zero for a free-standing film (reflecting boundary conditions) but nonzero when the film is sandwiched between two semi-infinite samples of the same material (outgoing boundary conditions). In the latter case, this resistivity scales inversely with the number of monolayers and is due to the background diffusive scattering by a finite lattice.

Breeding Bird Census On Four Shelterwood-Cut Stands In Buckingham County, Virginia, Sally Ann Statham

Theses & Honors Papers

The Breeding Bird Census (BBC) technique was used to study breeding bird populations on two paired shelter wood-cut oak stands in Buckingham County, Virginia. The four plots are part of a study to determine oak regeneration following controlled burns in the Virginia piedmont. There is an interest in determining how shelter wood-cut plots affect the breeding birds of Virginia. A total of twenty-seven bird species established and defended territories among the four plots. Ten bird species defended territories on all four plots. All of these species were birds characteristic of forest habitats.

Near-Band-Gap Cupt-Order-Induced Birefringence In Al0.48Ga0.52Inp2, Mathias Schubert, Tino Hofmann, Bernd Rheinlander, Ines Pietzonka, Torsten Sass, Volker Gottschalch, John A. Woollam

Department of Electrical and Computer Engineering: Faculty Publications

The order-induced birefringence in the near-band-gap spectral range (0.75 to 2.5 eV), and its dependence on the degree of ordering η is reported for Al_0.48Ga_0.52InP₂. Transmission and reflection generalized variable angle spectroscopic ellipsometry, dark-field spectroscopy, and cross-polarized reflectance difference spectroscopy (CRDS) are used to determine precisely the room-temperature dielectric functions for polarization parallel and perpendicular to the ordering direction of a series of spontaneously CuPt-ordered samples grown by metalorganic vapor-phase epitaxy. The CRDS technique is introduced as an approach to sense extremely weak anisotropy at oblique angles of incidence. The observed order birefringence is …

A Patching Model For Surface Tension Of Spherical Droplet And Tolman Length. Ii, T.V. Bykov, Xiao Cheng Zeng

Xiao Cheng Zeng Publications

In the framework of density functional theory (DFT), two patching models for the density profile of spherical liquid droplet are developed. The patching is based on analytical expressions of the asymptote of the density profiles. The first model leads to analytic expressions of the Tolman length and the effective rigidity constant, from which the temperature dependence of the Tolman length and effective rigidity constant can be determined. The second model is developed particularly for small spherical droplets, from which the dependence of chemical potential and the surface tension of the droplet on the radius are obtained. The results are compared …
